Rydex Investments Announces the Launch of CurrencyShares(SM) Japanese Yen Trust

New CurrencyShares(SM) ETF Tracks Price Movements of the Japanese Yen

ROCKVILLE, MD -- (MARKET WIRE) -- February 13, 2007 -- Rydex Investments today announced that shares
of the first yen-based exchange traded fund (ETF) will begin trading today
on the New York Stock Exchange. CurrencyShares Japanese Yen Trust (NYSE: FXY) tracks the daily price movement of its underlying currency, with
shares of the trust representing approximately 10,000 yen.

One of eight currency-based ETFs sponsored by Rydex, CurrencyShares
Japanese Yen Trust seeks to provide investors with a convenient and
cost-effective way to gain exposure to the currency markets.

"Due to its historically low correlation to equities and fixed income,
currency as an asset class may offer potential diversification benefits
when added to a portfolio," said Tim Meyer, ETF business manager at Rydex
Investments. "As the firm's newest currency-based ETF, CurrencyShares
Japanese Yen Trust offers an additional way for investors to gain access to
this non-correlating asset class."

Along with the potential diversification benefits of currency as an asset
class, the yen-based ETF provides investors with exposure to one of the
world's leading currencies. The Japanese yen, when paired with the U.S.
dollar, accounts for approximately 17% of global foreign exchange
transactions with an average daily turnover of approximately $296 billion.

The launch of CurrencyShares Japanese Yen Trust complements Rydex's
existing lineup of currency-based ETFs, which have collectively garnered
more than $1 billion in assets in less than a year.

The sponsor of CurrencyShares Japanese Yen Trust is Rydex Specialized
Products LLC, d/b/a Rydex Investments. The distributor of this exchange
traded fund is Rydex Distributors, Inc., an affiliate of Rydex Investments
and Rydex Specialized Products, LLC. M7 Ventures, LLC collaborated with
Rydex in connection to all CurrencyShares exchange traded products. The
Bank of New York (NYSE: BK) is the trustee of the trust and JPMorgan
Worldwide Securities Services (NYSE: JPM) is the depository for the trust.
